I installed pipenv by following the instructions here. From the Windows command prompt I ran
pip install --user pipenv
which returned the mess
Try adding the following to Path environmental variable:
C:\Users\Robert\AppData\Roaming\Python\Python36\Scripts
instead of the \site-package
, as that is where pipenv.exe is installed (at least for me).
Windows is not officially supported, I think.
